There are a couple of errors in your code.

(1).The condition (amt%5==0 && amt< balance) is incorrect.

Read the following line in problem statement:

pooja’s account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US.

That means for successful transaction , (amount pooja wants to withdraw+ the bank service charge <=Current balance in Pooja’s Account)

You are not considering the bank-charge.

So correct the above condition as:

 else if ((amt%5==0) && (amt+.5)<=balance)

(2)Also ,your code is missing else condition

Your code prints nothing when the three condition does not hold.

This is wrong ,youshould print the balance under such circumstances .

Please Read the problem statement again.

    if (amt%5!=0)
	{
		std::cout<<balance;
	}
	else if (amt%5==0&&amt+.5<=balance)
	{
		balance=balance-amt-0.5;
		std::cout<<balance;
	}
	else if (amt>=balance)
	{
		std::cout<<balance;
	}
	else
	{
	  std::cout<<balance;
	}

#include<stdio.h>
int main()
{
int x;
float y;
printf(“Input\n”);
scanf("%d %f",&x,&y);
if(x>0 && x<=2000 && y>=0 && y<=2000 && y-x-0.5>=0 && x%5==0)
y=y-x-0.50;
printf(“Output\n”);
printf("%f",y);
return 0;
}
WHAT WRONG IN THIS

CodeChef: Practical coding for everyone here is my solution
and you are getting a WA because your code is missing some corner conditions
